Even the CEO of Apple is surprised by how much time he spends on his devices.Tim Cook told CNN's Laurie Segall, in an exclusive TV interview, that he had a wake-up call about his own tech habits after seeing data from a newly unveiled Apple tool that will provide detailed reports of how much time users spend on the iPhone and iPad."I've been using it and I have to tell you: I thought I was fairly disciplined about this. And I was wrong," Cook told Segall in an interview after Apple's annual developer conference Monday.The feature, called Screen Time, shows users their daily and weekly time spent in each app and also lets them set time limits for specific apps. Users will also be able to see how many notifications they received and how often they picked up the device."When I began to get the data, I found I was spending a lot more time than I should," Cook told Segall, while declining to list which apps occupy the most of his time. "And the number of times I picked up the phone were too many."Screen Time was the centerpiece of what proved to be a key focus for Apple at the event Monday: Helping users build healthier relationships with their devices by limiting the constant digital distractions and better managing their time.Apple also expanded its Do Not Disturb feature to hide all notifications on the main screen at night when you're trying to sleep. Users can also set the Do Not Disturb option to automatically end when they leave a location or an event wraps up.Welcome to 2018, when tech companies hold major press events to introduce innovative ways to use their products less.The moves come amid broader scrutiny of the impact that tech is having on society, not just with fake news and election meddling, but also on users' personal well-being.Related: Tim Cook: I don't see politics in my futureApple investors pressured the company in January to do more to prevent excessive smartphone use among children and teenagers in particular.

"We're not focused on any singular company," he said."The privacy thing has gotten totally out of control," Cook said. "I think most people are not aware of who is tracking them, how much they're being tracked and sort of the large amounts of detailed data that are out there about them."At Apple, Cook told CNN, "We think privacy is a fundamental human right."
